Background technology

Along with the continuous development of electronic technology, infotech, automobile industry, wire harness is widely used.After wire harness was meant the contact element terminal and electric wire crimping that is formed by the copper material punching out, the outside is plastic compression insulator or added metal housing etc. again, tied up the assembly that forms connecting circuit with wire harness.

For guaranteeing the use safely and reliably of wire harness, must by product standard on the wire harness production line or before user's use it be carried out the strict process screening and replenish screening.At present wire harness manufacturer uses checkout equipment, mostly is that the multichannel both-end detects, minimum be 64 the tunnel, the 128 tunnel or the like, this testing of equipment speed is low, volume is bigger, complicated operation, production cost is higher, the detection of the small-sized wire harness of inapplicable production.

Summary of the invention

For solving the problem that exists in the prior art, the utility model provides a kind of 12 loops that are fit to the both-end wire harness distribution conduction detection device that places an order, mix the corresponding test fixture that has lock function, once plug together the back by the instrument internal DLC (digital logic circuit), can very convenient, accurately, promptly carry out the wire harness distribution conduction detection device of wire harness conduction detection.

The technical solution of the utility model is achieved in that wire harness distribution conduction detection device, comprise: locking head, solenoid valve, the source of the gas pipe of conduction detection instrument, pick-up unit, locking device, adversary's sheath, probe, wire harness to be checked, 15 hole plugs, band cylinder, it is characterized in that: the conduction detection instrument links to each other with the plug of pick-up unit by two 15 vent needles; Locking device is in parallel with pick-up unit.Open two holes on plank, the adversary sheath consistent with product to be detected put in two holes, and the size in hole is identical with adversary's sheath size, and blended rubber is fixed adversary's sheath; Open a hole in addition, one of them adversary's sheath will be closed in this hole, be used for fixing locking device, its size can just be passed through locking device, and locking device is fixed in the hole with screw, the cylinder tracheae partly of locking device is connected with source of the gas, and solenoid valve is connected on the tracheae, connected mode can adopt the butt joint of tracheae connector;

The probe and the wire bonds of test usefulness, the number of probe and product correspondence to be checked, probe inserts in adversary's sheath, and adversary's sheath all inserts probe, and probe is fixed in adversary's sheath with glue; The other end of the lead of linking probe links to each other with one of them 15 pin hole plug in each adversary's sheath, and links to each other with the conduction detection instrument with two 15 hole plugs.

The beneficial effects of the utility model are: be fit to the little wire harness conduction detection in the 12 loop scopes, a test function is arranged, by external test bar single-ended wire harness is carried out conduction detection.The continuous several times conduction detection is finally made the judgement that whether detects hit within a certain period of time.Instrument can be set the delay test function to overlength wire harness conduction detection.Testing result is reported to the police with sound, light, reminds operating personnel simultaneously exactly, to reduce the mistakes and omissions inspection.Be convenient in time find and open circuit, short circuit and loading error defective inefficacy products such as (wrong wire distributions).

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

Wire harness distribution conduction detection device comprises: locking head 8, solenoid valve 9, the source of the gas pipe of conduction detection instrument 1, pick-up unit 2, locking device 3, adversary's sheath 4, probe 5, wire harness to be checked 6,15 hole plugs 7, band cylinder.

The technical scheme that its technical matters that solves the utility model adopts is: the conduction detection instrument links to each other with the plug of detection frock by two 15 pin holes, and locking device is in parallel with verifying attachment.When product to be checked was certified products, conduction detection instrument pilot lamp was bright; Under the situation of not conducting, the buzzer warning that do not work of the pilot lamp on the detector, locking device is locked at product to be checked in the frock simultaneously.By the solenoid control source of the gas, thereby reach the purpose of locking or decontroling product to be detected.

The array mode of wire harness distribution conduction detection device, as shown in Figure 1, the main body of proving installation is a plank, mills two holes on plank, the adversary sheath 4 consistent with product to be detected put in two holes, the size in hole is identical with adversary's sheath size, and blended rubber is fixed adversary's sheath, mills a hole again, one of them adversary's sheath will be closed in this hole, be used for fixing locking device 3, its size can just by locking device just can, and with screw locking device is fixed on and mills in the good hole.

With the probe 5 and the wire bonds of test usefulness, the number of probe is relevant with product to be checked, and probe is inserted in adversary's sheath 4, after two adversary's sheaths all insert probe, probe is fixed in adversary's sheath with glue.The other end of the lead of linking probe in each adversary's sheath is linked to each other with one 15 vent needle plug 7, and will utilize these two 15 hole plugs to link to each other with conduction detection instrument 1.

The cylinder tracheae partly of locking device (3) is connected with source of the gas.And solenoid valve 9 is connected on the tracheae.Connected mode adopts the butt joint of tracheae connector to get final product.

Principle of work (as shown in Figure 3)

Output control function is controlled by the conduction detection instrument.Wherein K1 is a relay, and C is for being power filtering capacitor.K1 closure during work, U1 exports 24 volts of direct supplys, and when detecting qualified wire harness, K1 disconnects, and U1 does not have 24 volts of voltage inputs;

Test fixture is controlled by K2 pin type switch, K3 pushbutton switch, 24 volts of solenoid valves of D direct current, R current-limiting resistance, compositions such as luminous 2 utmost point pipes of V.Its principle of work is a K2 closure behind the adversary's sheath on the detected wire harness insertion frock, and solenoid valve D connects the back and drives cylinder work, with detected wire harness locking;

(judged by detector) that after detected wire harness is qualified K1 disconnects U1 does not have 24 volts of voltage outputs, solenoid valve D outage drives cylinder work, and locking device unclamps, and detected wire harness is let pass;

When detected wire harness is defective, press the K3 switch, detected wire harness is let pass, and inferior product is a unacceptable product;

V is luminous 2 utmost point pipes, and R is a current-limiting resistance, after detected wire harness inserts adversary's frock, and the K2 closure, led lighting, wire harness detect qualified back K1 and disconnect, and diode is not luminous.

Using method:

Two 15 hole blind plugs 7 on the checking device are linked to each other with two sockets on the conduction detection instrument 1 respectively;

The set condition of adjusting on the pick-up unit is the conduction detection state;

Insert wire harness 6 to be checked, solenoid valve locking 9 this moment, if wire harness to be detected is certified products, the qualified display lamp of detector is bright, this product is qualified.The solenoid valve outage, product is released; If unacceptable product, the conduction detection instrument is shown as defective, the buzzer warning on the conduction detection instrument.
